Abstract

A coupling device (32) provides a rotary coupling of a pivot shaft (18) of a flap diaphragm (16) of an exhaust gas flap (10) with a drive element (34). The pivot shaft is to be rotated about a pivot axis (A). The coupling device (32) includes a first coupling part (36) with a first coupling area configured for coupling with the pivot shaft (18) and a second coupling part (38) with a second coupling area configured for coupling with the drive element (34). The first coupling part (36) and the second coupling part (38) are in a rotary coupling positive-locking meshing state with one another in the coupled state and are supported on one another in the direction of the pivot axis (A).
