Abstract

A coupling arrangement is disclosed for the rotational coupling of a drive element of a pivoting drive of an exhaust-gas flap for the exhaust-gas flow of a combustion engine to a pivot shaft rotatable about a pivot axis. A first coupling element has a coupling region coupled to a pivot shaft for rotation about the pivot axis. A preload element generates a force acting on the first coupling element and the second coupling element in a peripheral direction with respect to one another and generates a force acting in an axial direction between the coupling elements. One of the coupling elements includes two radially outwardly extending rotational coupling projections and the other coupling element includes a rotational coupling cutout receiving the projection. The one coupling element is held axially on the other coupling element by the preload element to prevent the projections from moving out of the cutouts.
