Claim 6:
7. A turbocharger comprising:
(A) a setting element configured to influence an operation of the turbocharger;
(B) a turbocharger actuator arrangement for the turbocharger, the turbocharger actuator arrangement comprising;
a movable actuator operating lever,
a control rod couplable to the setting element of the turbocharger and which is connected by a bolt to the actuator operating lever such that the control rod is arranged to be rotatable relative to the actuator operating lever, and
a wave spring having an undulating form with alternating undulation peaks and troughs,
wherein the bolt extends from the actuator operating lever through an opening in an end region of the control rod and through the wave spring, such that the control rod and the wave spring are arranged between the actuator operating lever and a bolt securing means, which is arranged at an end region of the bolt averted from the actuator operating lever,
wherein the wave spring is arranged between the control rod and the actuator operating lever,
wherein the bolt is fixedly connected to the actuator operating lever,
wherein the bolt has a first region entirely between the control rod and the actuator operating lever and a second region between the first region and the end region, and the second region runs through the opening of the control rod, and the first region and the end region of the bolt are situated outside the opening of the control rod, and
wherein a diameter of the second region is smaller than a diameter of the first region such that the bolt centers the wave spring, and

(C) an actuator configured to control the turbocharger by varying a position of, or moving, the actuator operating lever, wherein the control rod is coupled to the setting element of the turbocharger such that the variation of the position, or movement, of the actuator operating lever causes a variation of the position, or movement, of the setting element, and wherein the setting element is one out of the group comprising a bypass valve, a VTG cartridge and a regulating flap.
