ABSTRACT:
Coupling apparatus includes a bracket fixed to the housing of an air motor and an actuator mechanism 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, a retaining bar being pivotal between a release position accommodating movement of the apparatus into coupling engagement with the valve and a retaining position preventing movement from coupling engagement. A guard telescopes around the motor housing and is manually movable axially thereof between a use position enshrouding the handwheel and the actuator and a retracted position exposing the handwheel and the actuator,
