Patent ID: 8789807

Claim:
A quick disconnect actuator coupler for mounting an actuator to a valve or damper of an HVAC system, comprising: a base encircling a rotational axis of a rotational control member of the valve or damper, the rotational control member being moveable about the rotational axis between an open position wherein the valve or damper permits flow and a closed position wherein the valve or damper permits less flow or no flow to at least one outlet, the base being securable to a valve housing or damper housing via assembly substantially exclusively in an axial direction so the base encircles the rotational control member; an actuator mount encircling the rotational axis, the actuator mount being securable to an actuator body; wherein the base and the actuator mount have a mating relationship which allows sliding assembly of the actuator mount to the base in an axial direction, which when mating define at least one hole in both the base and the actuator mount extending transversely relative to the rotational axis, the mating relationship preventing rotational movement of the actuator mount relative to the base, the mating relationship preventing lateral movement of the actuator mount relative to the base; and a bail which slides into the hole to secure the actuator mount to the base against axial movement, with the rotational control member being rotational within the joined actuator mount/base for rotational movement caused by the actuator, sliding of the bail out of the hole allowing toolless removal of the actuator from the valve or damper.
