Zusammenfassung:A coupling device, for the rotary coupling of a pivot shaft of a flap diaphragm of an exhaust gas flap with a drive element, includes at least one coupling element (36) with a first coupling area (40) configured for coupling to the pivot shaft (18), with a second coupling area (42) configured for coupling to the drive element (34) and with at least one connection area (52, 58) connecting the first coupling area (40) to the second coupling area (42). In the coupled state, the first coupling area (40) and the second coupling area (42) are prestressed in a direction towards one another or in a direction away from one another. The at least one coupling element (36) is formed with sheet material.
