The invention relates to an apparatus for coupling a shaft or a hub by means of a radially resilient bush, which can be radially clamped to the shaft or hub by axially tightenable clamping elements by exposing the clamping elements to a radially operative spring assembly; the release of the coupling is effected by means of a hydraulically- or pneumatically-actuated cylinder and piston arrangement. The nucleus of the invention is that the spring assembly is accommodated in the cylinder chamber acted upon by the pressure fluid. |
