Claim Text:
1. An actuating device ( 10 ) for a turbine of an exhaust gas turbocharger for controlling a charging pressure of the exhaust gas turbocharger, the turbine having a valve with an actuating shaft ( 12 ), which is rotatable about an axis of rotation ( 14 ) for actuating the valve between a first position and a second position, the actuating device comprising a connecting arm ( 20 ) coupled at one end thereof to the actuating shaft ( 12 ) for rotation therewith, an actuating link ( 26 ) coupled to the connecting arm ( 20 ) by a connecting bolt ( 22 ) mounted on the actuating link ( 26 ) and extending through an opening in the connecting arm ( 20 ) along an axis which extends parallel to the axis of rotation ( 14 ) of the actuating arm shaft ( 12 ), the actuating shaft ( 12 ) being rotatable about its axis of rotation ( 14 ) by translatory motion of the actuating link ( 26 ), the connecting arm ( 20 ) being held in engagement with actuating shaft ( 12 ) and with the connecting bolt ( 22 ) by an integral intermediate locking element ( 28 ) extending along a first side 30 ) of the connecting arm ( 20 ), one of the actuating shaft ( 12 ) and the connecting bolt ( 22 ) being engaged, at a second side ( 32 ) of the connecting arm ( 20 ) facing away from the first side ( 30 ) of the connecting arm ( 20 ), by the intermediate locking element ( 28 ) for retaining the connecting arm ( 20 ) in engagement with the connecting bolt ( 22 ) and, via the connecting bolt ( 22 ), with the actuating link ( 26 ).
