ABSTRACT:
A quick change coupling arrangement for holding an actuator shaft of a hydraulic dampening unit to a valve shaft of a swing check valve. The coupling arrangement provides knob portions arranged on opposing free ends of the valve shaft and the actuator shaft, which are captured in sandwich fashion between two semi-circular cylindrical shell connectors. An outer sleeve is provided which can be temporarily displaced upward on the actuator shaft during assembly of the shell sections over the knob portions and then slid downward to cover the shell sections and hold the shell connectors together preventing radial departure from the knob portions. A set screw is provided to hold the sleeve in axial fixation with one of the shell connectors.
