1. A mechanical sensor coupled to an actuator, the mechanical sensor being operable to detect when the actuator is fully installed on a valve, the mechanical sensor comprising: an actuation disk configured for reciprocal, axial movement within a bore defined in a nose piece of the actuator;a location disk configured for reciprocal axial movement within the bore defined in the nose piece of the actuator;a sensor axially interposed between the actuation disk and location disk;wherein when the actuator is installed on a valve, a portion of the valve contacts the actuation disk and moves the actuation disk back against the sensor to indicate that the actuator is fully installed on the valve; andwherein the actuation disk and location disk are rotationally fixed relative to one another about a center longitudinal axis of the mechanical sensor by an anti-rotational arrangement. 2. The mechanical sensor of claim 1, further comprising an adaptor, with the adaptor configured for rotational engagement with the nose piece and the valve. 3. The mechanical sensor of claim 1, wherein the anti-rotational arrangement is formed by a first key and first keyway receiving the first key, and a second key and a second keyway receiving the second key. 4. The mechanical sensor of claim 3, wherein the first key is formed on the nose piece, and the first keyway is formed on the actuation disk, and wherein the second key is formed on the actuation disk and the second keyway is formed on the location disk. 5. The mechanical sensor of claim 1, wherein the anti-rotational arrangement is formed by a key and a keyway receiving the key, and a boss and a termination bore receiving the boss. 6. The mechanical sensor of claim 5, wherein the key is formed on the actuation disk and the keyway is formed on the location disk, and wherein the boss is formed on the location disk and the termination bore is formed on the nose piece. 7. The mechanical sensor of claim 5, wherein the key is formed on the nose piece and the keyway is formed on the actuation disk, and wherein the boss is formed on the location disk and the termination bore is formed on the nose piece. 8. The mechanical sensor of claim 1, wherein the sensor is a pressure sensitive film device configured to detect a pressure between the actuation disk and location disk. 9. A mechanical sensor coupled to an actuator, the mechanical sensor being operable to detect when the actuator is fully installed on a valve, the mechanical sensor comprising: an actuation disk configured for reciprocal, axial movement within a bore defined in a nose piece of the actuator;a location disk configured for reciprocal, axial movement within the bore defined in the nose piece of the actuator;a sensor axially interposed between the actuation disk and location disk;wherein when the actuator is installed on a valve, a portion of the valve contacts the actuation disk and moves the actuation disk back against the sensor to indicate that the actuator is installed on the valve; andwherein the nose piece includes a termination bore, and the location disk includes an aperture aligned coaxially with the termination bore, and wherein the sensor includes lead wires which pass through the aperture of the location disk and through the termination bore of the nose piece. 10. The mechanical sensor of claim 9, wherein the aperture of the location disk and the termination bore of the nose piece are coaxially aligned along an axis which is parallel to and radially offset from a center longitudinal axis of the mechanical sensor. 11. An actuator for a valve, the actuator comprising: an actuator housing;a nose piece coupled to the housing;a bore defined in the nose piece;an actuation disk disposed in the bore of the nose piece;a location disk disposed in the bore of the nose piece, the actuation disk and location disk axially movable within the nose piece;a bias member disposed in the nose piece, the bias member configured to force the location disk against a sensor which is in turn forced against the actuation disk;wherein the sensor is a pressure sensitive film device configured to detect a pressure between the actuation disk and location disk. 12. A mechanical sensor coupled to an actuator, the mechanical sensor being operable to detect when the actuator is fully installed on a valve, the mechanical sensor comprising: an actuation disk within a bore defined in a nose piece of the actuator;a location disk within the bore defined in the nose piece of the actuator;a sensor axially interposed between the actuation disk and location disk; andwherein the actuation disk and location disk are rotationally fixed relative to one another about a center longitudinal axis of the mechanical sensor by an anti-rotational arrangement. 13. The mechanical sensor of claim 12, wherein the anti-rotational arrangement is formed by a first key and first keyway receiving the first key, and a second key and a second keyway receiving the second key. 14. The mechanical sensor of claim 13, wherein the first key is formed on the nose piece, and the first keyway is formed on the actuation disk, and wherein the second key is formed on the actuation disk and the second keyway is formed on the location disk. 15. The mechanical sensor of claim 12, wherein the anti-rotational arrangement is formed by a key and a keyway receiving the key, and a boss and a termination bore receiving the boss. 16. The mechanical sensor of claim 15, wherein the key is formed on the actuation disk and the keyway is formed on the location disk, and wherein the boss is formed on the location disk and the termination bore is formed on the nose piece. 17. The mechanical sensor of claim 15, wherein the key is formed on the nose piece and the keyway is formed on the actuation disk, and wherein the boss is formed on the location disk and the termination bore is formed on the nose piece. 18. The mechanical sensor of claim 12, wherein the sensor is a pressure sensitive film device configured to detect a pressure between the actuation disk and location disk. 19. The mechanical sensor of claim 12, wherein when the actuator is installed on a valve, a portion of the valve contacts the actuation disk and moves the actuation disk back against the sensor to indicate that the actuator is fully installed on the valve.
