ABSTRACT:
The coupling between a sub-sea pipeline valve and its actuator is brought about by the adoption of a device (4) associated rigidly with the housing of the valve and provided with a hollow shaft (6) into which the valve shaft is keyed. The top of the hollow shaft affords a ring of dogs (7) designed to engage matching dogs (8) carried by a sleeve (9) driven by the pistons of the hydraulic actuator through a mechanical linkage, so that the movement which opens and closes the valve is transmitted through an easily coupled and decoupled dog-clutch; the stationary part of the device (4) is provided with torque reaction lugs (20, 21) which occupy sockets (22) formed in the casing of the actuator.
