A coupling arrangement is disclosed for rotationally coupling a drive element of a pivoting drive of an exhaust-gas flap for the exhaust-gas flow to a pivot shaft that is rotatable about a pivot axis. A first coupling element has a coupling region coupled to the pivot shaft for conjoint rotation about the pivot axis and a second coupling element has a coupling region coupled to the drive element for conjoint rotation about the pivot axis. A preload element acts on the first coupling element and the second coupling element substantially in a peripheral direction with respect to one another. One of the coupling elements has two rotational coupling projections which extend radially outward with respect to the coupling region of the coupling element. The other coupling element includes, so as to be assigned to each rotational coupling projection, a rotational coupling cutout which receives the corresponding rotational coupling projection.
