1. A door lock apparatus, comprising in combination: a) a housing,b) a handle protruding from the housing,c) a latch device disposed within the housing, the latch device configured for being positioned between a locked position and an unlocked position,d) a first coupler mechanism disposed in the housing and configured for selectively enabling force transmission between the handle and the latch device when in an engaged position to move the latch device between the locked and unlocked positions,e) an actuating mechanism disposed within the housing,f) a cam operatively connected to the actuating mechanism, the cam including a lobe, andg) a cam follower assembly including a body rotatably mounted to the housing about an axis, a cam follower operatively engaged with the lobe, and a resilient biasing mechanism operatively engaged with the first coupler mechanism,wherein the actuating mechanism is configured to position the cam so that the lobe engages the cam follower and rotates the body about the axis so that the resilient biasing mechanism places the first coupler mechanism in the engaged position to provide for force transmission between the handle and the latch device. 2. The combination of claim 1 wherein the actuating mechanism includes an electronic motor. 3. The combination of claim 1 wherein the first coupler mechanism includes a clutch plate and a coupler, wherein the coupler is selectively engageable with the clutch plate by the cam lobe, wherein, when engaged, the clutch plate drives the coupler. 4. The combination of claim 1 wherein said resilient biasing member is a leaf spring engageable with the first coupler mechanism. 5. The combination of claim 3 wherein one of the coupler or the clutch plate includes a pin radially displaced outward from a first rotational axis of the one of the coupler or the clutch plate and extending outward in a direction parallel to the first rotational axis, and the other of the coupler or the clutch plate includes a slot extending radially from a second rotational axis of the other of the coupler or the clutch plate and extending in a direction parallel to the second rotational axis, and wherein the pin engages the slot to affect the selective engagement of the clutch plate and the coupler. 6. The combination of claim 1 wherein the handle includes a second coupler mechanism engageable with the first coupler mechanism, wherein the second coupler mechanism includes a shaft fixedly connected to the handle and wherein the shaft is decouplable from the first coupler mechanism. 7. The combination of claim 1 wherein said first coupler mechanism includes a detent, wherein a second coupler mechanism includes a ball and a spring, wherein said ball is biased by said spring and configured for engagement with said detent, and wherein said engagement of said ball with said detent resists relative rotational movement between said first coupler mechanism and said second coupler mechanism. 8. A combination of claim 1, wherein the housing is mountable to a door by a first fastener, the combination comprising: a cover releasably mounted to the housing by a second fastener, the cover positioned to block access to the first fastener when the cover is mounted to the housing;a key lock configured for being selectively positioned between a locked position and an unlocked position, wherein the latch device is adapted to lock the door to a door frame when the key lock is in the locked position, and wherein the latch device is adapted to allow the door to be unlocked from the door frame when the key lock is in the unlocked position; andan override bracket operatively connected with the key lock and movable between a first position and a second position,wherein the override bracket is in the first position when the key lock is in the locked position to block access to the second fastener so that the cover is not releasable and access to the first fastener is blocked by the cover, andwherein the override bracket is in the second position when the key lock is in the unlocked position to provide access to the second fastener so that the cover is releasable and the first fastener is accessible. 9. The combination of claim 1, wherein said body of said cam follower assembly includes a first end and a second end, wherein said cam follower is disposed on said first end, wherein said resilient biasing mechanism is disposed on said second end, wherein said cam follower directly engages the lobe, and wherein said resilient biasing mechanism directly engages the first coupler mechanism. 10. A door lock apparatus, comprising in combination: a) a housing,b) a handle protruding from the housing,c) a latch device disposed within the housing, the latch device configured for being positioned between a locked position and an unlocked position,d) a first coupler mechanism disposed in the housing and configured for selectively enabling force transmission between the handle and the latch device when in an engaged position to move the latch device between the locked and unlocked positions,e) an actuating mechanism disposed within the housing,f) a cam operatively connected to the actuating mechanism, the cam including a lobe and a body portion extending axially from the lobe, wherein the body portion includes a first magnet attached to a surface of the body portion and a second magnet attached to the surface of the body portion and disposed radially away from the first magnet, and wherein the housing includes a Hall Effect sensor aligned with the body portion and configured to sense the rotational position of the cam, andg) a cam follower assembly including a body rotatably mounted to the housing about an axis, a cam follower operatively engaged with the lobe, and a resilient biasing mechanism operatively engaged with the first coupler mechanism,wherein the actuating mechanism is configured to position the cam so that the lobe engages the cam follower and rotates the body about the axis so that the resilient biasing mechanism places the first coupler mechanism in the engaged position to provide for force transmission between the handle and the latch device. 11. A door lock apparatus mountable to a door, the door lock apparatus comprising: a latch device for selectively locking the door to a door frame;a housing mountable to the door by a first fastener;a cover releasably mounted to the housing by a second fastener, the cover positioned to block access to the first fastener when the cover is mounted to the housing;a key lock configured for being selectively positioned between a locked position and an unlocked position, wherein the latch device is adapted to lock the door to the door frame when the key lock is in the locked position, and wherein the latch device is adapted to allow the door to be unlocked from the door frame when the key lock is in the unlocked position; andan override bracket operatively connected with the key lock and movable between a first position and a second position;a biasing member mounted to the housing; anda crank cover including a protruding feature extending from the crank cover,wherein the override bracket is in the first position when the key lock is in the locked position to block access to the second fastener so that the cover is not releasable and access to the first fastener is blocked by the cover,wherein the override bracket is in the second position when the key lock is in the unlocked position to provide access to the second fastener so that the cover is releasable and the first fastener is accessible,wherein the biasing member biases the override bracket in a first direction so that the override bracket does not contact the protruding feature when moving from the first position to the second position, andwherein the protruding feature is configured for contacting the override bracket when moving from the first position to the second position when a force is applied to the override bracket in a second direction that is opposite the first direction. 12. A door lock apparatus in accordance with claim 11, further comprising a biasing member mounted to the housing, wherein the biasing member biases the override bracket toward the first position. 13. A door lock apparatus in accordance with claim 11, wherein the key lock includes a key cylinder and a cam, and wherein the cam is configured for moving the override bracket to the second position when the key lock is in the unlocked position. 14. A door lock apparatus in accordance with claim 11, wherein an aperture is defined in the housing, and wherein the second fastener is accessible through the aperture when the override bracket is in the second position. 15. A door lock apparatus in accordance with claim 11, wherein the cover is a battery cover.
