ABSTRACT:
Coupling apparatus includes a bracket fixed to the housing of an air motor and an actuator member fixed to the rotary output shaft of the air motor for coupling the air motor in driving engagement with a handwheel-operated valve for remote power actuation thereof. The apparatus is freely movable into and out of coupling engagement with the valve in directions axially of the valve stem without the use of tools, the actuator legs being movable into rotating engagement with the handwheel for rotation thereof simultaneously with movement of the bracket into non-rotatable engagement with the valve body for anchoring the motor housing and preventing rotation thereof with its output shaft. Two embodiments are disclosed, one for use with a valve having a solid handwheel and a yoke and the other for use with a valve having a spoked handwheel and no yoke.
