The invention relates to a device for providing a friction joint by pressing a number of first elements against a second element by means of a pressure medium acting on said first elements. In order to obtain an improved ability of transmitting a torque and an improved stability regarding radial load, said first elements are so arranged that they encircle or are encircled by said second element and are acted upon by a number of mutually independent portions of the pressure medium, each portion acting on its own element. |
