ABSTRACT:
A pressurized hydraulic fluid actuated coupling assembly for detachably coupling to an element. The assembly has first and second concentric walls secured together at the ends. The second wall is adapted for engaging the element. One of the walls has grooves defining corresponding recesses between the first and second walls. Ridges on such one wall are defined between adjacent recesses. Means is provided for introducing hydraulic fluid into the recesses. Means is provided for varying the pressure of the hydraulic fluid such that in the absence of fluid pressure, the ridges on the one wall are in contact with the other wall and upon pressurization of the fluid the second wall moves away from the first wall such that the second wall rigidly couples to the element and such that the ridges are spaced a predetermined distance from the other wall.
