A pair of torque-transmitting members are joined together in torque-transmitting relationship at an inner and outer tubular connecting part of each by connecting elements interposed within an annular recess formed between said inner and outer connecting parts, said connecting elements having acuminated portions and being formed of a material harder than the material of the connecting parts in order to penetrate the surface thereof when the connecting parts are pressed together thereby to hold the first and second members in torque-transmitting engagement. |
