Coupling device comprising rotation damping structure

A coupling device comprising:

• a universal joint connected to a first support member and a second support member, the universal joint allowing relative rotation between the two support members about a first axis and a second axis perpendicular to the first axis;
• and
• a rotation damping structure comprising four damping elements, each damping element comprising a base section, a connector section, and a yielding section extending between the base section and the connector section, the yielding section being configured to plastically deform by a relative rotation (ωX, ωY) between the base section and the connector section;
• wherein a first pair of the damping elements are arranged on opposite sides of the universal joint along the first axis, wherein the base sections of each of the first pair of damping elements are fastened to the first support member;
• wherein a second pair of the damping elements are arranged on opposite sides of the universal joint along the second axis, wherein the base sections of each of the second pair of damping elements are fastened to the second support member;
• and
• wherein the connector sections of each of the first pair of damping elements are fastened to the connector sections of each of the second pair of damping elements such that the connector sections of the four damping elements form a rigid loop around the universal joint.
