Abstract
A coupling device couples a drive shaft of a pivot drive () of an exhaust gas stream exhaust flap () for an internal combustion engine with a pivot shaft (), which is rotatable about a pivot axis (A) and carries a flap member (). The coupling device includes a coupling element () with a first coupling area () positive-locking engaging with a drive shaft () and with a second coupling area () positive-locking engaging with a pivot shaft. A prestressing element () is supported in relation to the coupling element and in relation to a support element () and prestresses the coupling element in a direction of a coupling axis (K), axially away from the support element and in a circumferential direction. A preassembly-blocking device () holds the support element under axial prestress and circumferential prestress in a preassembled position in relation to the coupling element.
