Abstract: In an actuating device for an exhaust gas turbocharger for adjusting the charging pressure of the exhaust gas turbocharger, including a valve element which is coupled with an actuating element of the actuating device via at least one intermediate element and which is adjustable via the actuating element between a first position in which a duct of the exhaust gas turbocharger through which exhaust gas may flow is at least partially opened and another position in which the duct is at least partially blocked, the intermediate element which comprises a first end region and a second end region is coupled with the valve element and the actuating element, the intermediate element at its second end region being rotatable about a third axis of rotation relative to the valve element and is coupled with it and at its first end region is rotatable about a second axis of rotation which extends essentially perpendicular to the third axis of rotation relative to the actuating element with which it is also coupled.
