Abstract: A brake device including a first device; a brake element having a first frictional brake surface and an engageable structure; a second device movable relative to the first device; a second frictional brake surface; a force device arranged to press the first frictional brake surface and the second frictional brake surface against each other with a pressing force; and an actuator connected to the first device, the actuator including an engaging structure movable between a disengaged position not engaging the engageable structure, and an engaged position engaging the engageable structure to brake relative motion between the first device and the second device; wherein a dynamic friction coefficient between the first frictional brake surface and the second frictional brake surface is less than 0.3, such as less than 0.15, or less than 0.1; and wherein the pressing force is dimensioned with respect to the dynamic friction coefficient.

Abstract: A coupling device including two support members; a joint connecting the two support members and allowing relative rotation between the support members about at least one rotational axis; and at least one damping element connecting the two support members in parallel with the joint; wherein the at least one damping element is configured to deform plastically by a relative rotation between the support members about the at least one rotational axis. A support structure for supporting a mass, a method for adjusting the stiffness of a coupling device and a method for providing stiffness to a coupling device are also provided.
