Abstract
The invention contemplates a simple coupling means for interfacing linear acting actuator shafts with valves or hydraulic chokes. The coupling means of the present invention allows either an actuator or an interconnected valve or choke to be rapidly, safely, and efficiently interchanged with a replacement part. The present invention is broadly applicable to a wide variety of actuator types having rectilinear motion outputs and to a large variety of valve and choke types which are operated by linear motions, including gate valves with or without balanced stems.
