ABSTRACT:
A coupling is mounted between a valve stem of a valve and a rod of a valve actuator. A first fitting of the coupling is mounted on an end of the rod and a second fitting is mounted on an adjacent end of the stem. The first fitting includes an opening therein which loosely entraps an expanded portion of the second fitting. The first and second fittings respectively have aligned surfaces which are generally perpendicular to the rod and stem. The surfaces make contact during movement of the rod toward the valve for closure of the valve. A resiliently deflectable spring is disposed between the first and second fittings to limit the amount of force transmitted to the valve through the stem when the rod is in a position for backseating the valve.
