A valve actuator assembly includes a rotatable member carrying an extendable indicator arm. The extendable indicator arm may be moveable between a retracted position and an extended position. When the extendable indicator arm is in the extended position, the extendable indicator arm may extend laterally past side walls of the actuator housing of the valve actuator assembly, such that the extendable indicator arm is visible from a location below the valve actuator assembly.

1. A valve actuator assembly for rotating a rotatable input of a valve, the valve actuator assembly comprising: a rotatable output couplable to the rotatable input of a valve;a drive mechanism for rotating the rotatable output;an actuator housing having a top portion and a bottom portion, with a side wall extending between the top portion and the bottom portion;a rotatable member disposed adjacent the top portion of the actuator housing, the rotatable member rotating with rotation of the rotatable output along a range of motion; andan extendable indicator arm that is selectively extendable from the rotatable member, the extendable indicator arm having a retracted position and an extended position, wherein the extendable indicator arm is slidably disposed within a channel in the rotatable member. 2. The valve actuator assembly of claim 1, wherein, when the extendable indicator arm is in the extended position, the extendable indicator arm extends laterally past the side wall of the actuator housing along at least a major portion of the range of motion of the rotatable member. 3. The valve actuator assembly of claim 2, wherein, when the extendable indicator arm is in the extended position, the extendable indicator arm is visible from the bottom portion of the actuator housing along at least a major portion of the range of motion of the rotatable member. 4. The valve actuator assembly of claim 1, wherein the extendable indicator arm has a first end and a second end, wherein the second end includes a pair of flexible members. 5. The valve actuator assembly of claim 4, further comprising an outwardly extending tab disposed on each of the flexible members. 6. The valve actuator assembly of claim 5, wherein the channel in the rotatable member extends from an inward end having a tapered enlarged region to an outward end that exits the rotatable member. 7. The valve actuator assembly of claim 6, further comprising a pair of intermediate recesses disposed within the channel between the inward end and the outward end. 8. The valve actuator assembly of claim 7, wherein the outwardly extending tabs of the flexible members are configured to selectively engage the enlarged region of the channel in the retracted position and the intermediate recesses of the channel in the extended position. 9. A valve actuator assembly, for connection to a valve, the valve actuator assembly comprising: an actuator housing having a top portion and a bottom portion, with a side wall extending between the top portion and the bottom portion;a rotatable member disposed adjacent the top portion of the actuator housing, the rotatable member including a channel, the channel having a first end to a second end, the rotatable member rotating along a range of motion;an extendable indicator arm slidably disposed within the channel of the rotatable member, the extendable indicator arm configured to slide between a retracted position and an extended position;wherein, when the extendable indicator arm is in the extended position, the extendable indicator arm extends laterally out past the side wall of the actuator housing along at least a major portion of the range of motion of the rotatable member. 10. The valve actuator assembly of claim 9, wherein, when the extendable indicator arm is in the retracted position, the extendable indicator arm does not extend laterally out past the side wall of the actuator housing along the range of motion of the rotatable member. 11. The valve actuator assembly of claim 9, wherein the first end of the channel includes an enlarged region. 12. The valve actuator assembly of claim 11, further comprising a first intermediate recess disposed on a first side of the channel and a second intermediate recess disposed on the second side of the channel, the first and second intermediate recesses disposed intermediate between the first end of the channel and the second end of the channel. 13. The valve actuator assembly of claim 11, wherein the extendable indicator arm has a first end and a second end, the second end of the extendable indicator arm includes a first flexible member and a second flexible member, with a first tab extend laterally out from the first flexible member and a second tab extending laterally out from the second flexible member. 14. The valve actuator assembly of claim 13, wherein, when the extendable indicator arm is in the retracted position, the first tab and the second tab engage the enlarged region of the channel. 15. The valve actuator assembly of claim 13, wherein, when the extendable indicator arm is in the extended position, the first tab and the second tab engage the intermediate recesses in channel. 16. A valve actuator assembly, for connection to a valve, the valve actuator assembly comprising: a rotatable output couplable to a valve for setting a current position of the valve;an actuator housing having a top portion and a bottom portion, with a side wall extending between the top portion and the bottom portion;a rotatable member disposed adjacent the top portion of the actuator housing, the rotatable member rotating with rotation of the rotatable output along a range of motion and indicating the current position of the valve; andan extendable indicator that is slidably received by the rotatable member and that is selectively extendable from the rotatable member between a retracted position and an extended position, wherein when the extendable indicator is in the extended position, the extendable indicator extends laterally out past the side wall of the actuator housing along at least a major portion of the range of motion of the rotatable member, and when the extendable indicator is in the retracted position, the extendable indicator does not extend laterally out past the side wall of the actuator housing. 17. The valve actuator assembly of claim 16, wherein, in the extended position, the extendable indicator releases from the rotatable member if a sufficient lateral force is applied to the extendable indicator without causing damage to the rotatable member.
