A motor operated valve which includes a valve actuated by rotation of the valve stem, a rotary electric motor supported on the valve by a bracket which maintains the motor shaft and valve stem in axial alignment, and a two-piece coupling for drivably connecting the motor shaft and valve stem together. The two pieces of the coupling are angularly adjustable so that the relationship of the initial angular orientations of the motor shaft and of the valve stem can be set without disassembly of the valve or removal of the motor cover. The two pieces of the coupling abut through opposed toothed circular surfaces which rotate with respect to each other and bolt together to lock the coupling in the desired position.

A motor operated valve assembly comprising: a valve housing a rotatable valve contained within said housing, said valve being movable between a fully open and a fully closed position, a valve stem carried by said rotatable valve and extending from said housing, a bracket rigidly mounted on said valve housing, a motor rigidly mounted to said bracket and having a rotatable output shaft extending toward and in axial alignment with said valve stem, said motor having a motor housing and switches contained internally of said motor housing for delineating the fully open and fully closed position of said valve, and a coupling having an axis in axial alignment with said shaft and having first and second pieces both axially adjustable and angularly adjustable with respect to each other, said first piece being drivably connected to said shaft and said second piece being drivably connected to said stem, said coupling pieces being axially movable into driving engagement with each other after said motor has been moved to one limit of its travel as determined by said switches and said valve has been moved to one of its fully open or fully closed positions.
