Abstract:
1. A coupling for securing a first element to a second element, the coupling comprising: an actuation bolt which comprises a longitudinal axis; a clamping jaw which is mounted on the first element and which comprises a bore having a first part which defines a nut that threadedly engages the actuation bolt and a second part within which the actuation bolt extends; and torque limitation means positioned between the actuation bolt and the second part of 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; wherein when an external force acting on the clamping jaw is greater that the force generated against the bore by the torque limitation means, rotation of the actuation bolt will result in translation of the clamping jaw along the axis; and wherein when the external force acting on the clamping jaw is less than the force generated against the bore by the torque limitation means, rotation of the actuation bolt will rotate the clamping jaw about the axis.
