ABSTRACT:
A coupling has respective support elements extending respectively from each coupling end toward the other, but not directly connected to each other. Radially oriented ends of these elements define a pocket capturing a cushion therein. A non-metallic bellows operably covers the coupling. An optional thermal shield is disposed between the bellows and the support element.
