Abstract
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.
