Abstract
A coupling for securing a first element to a second element includes an actuation bolt, a clamping jaw mounted on the first element which comprises a bore having a threaded part which defines a nut that threadedly engages the actuation bolt, and a torque limitation device positioned between the actuation bolt and the bore for transmitting the rotational movement of the actuation bolt directly to the clamping jaw to thereby rotate the clamping jaw about the axis. In operation, when an external force acting on the clamping jaw is greater that the force generated against the bore by the torque limitation device, rotation of the actuation bolt will result in translation of the clamping jaw, and when the external force acting on the clamping jaw is less than the force generated against the bore by the torque limitation device, rotation of the actuation bolt will rotate the clamping jaw about the axis.
