The invention relates to a regulating device for a turbocharger, wherein the regulating device (1) is received in a turbocharger exhaust gas conducting section through which exhaust gas can flow, andwherein a fluid flow to a turbine wheel which is rotatably received in the exhaust gas conducting section can be conditioned using the regulating device. A flow opening which is formed in the exhaustgas conducting section is to be opened and closed using a valve element (2) of the regulating device (1), wherein the valve element (2) is arranged on a pivot arm (4) of the regulating device (1), which pivot arm (4) can be pivoted about an axis of rotation (17), and wherein the valve element (2) has a valve body (5) comprising an insert element (7) that is largely received in a hollow chamber (29) of the valve body (5) and is operationally connected to the pivot arm (4), more particularly with the aid of a lever arm (3), and wherein the valve element (2) has a sealing surface (22) to avoid aleak in a closed position of the regulating device (1). According to the invention, particularly for reducing secondary torques acting on the valve element (2) during operation, a connection is formedbetween the pivot arm (4) and the valve element (2) in or at least close to a centre of gravity of an effective valve element body (31) of the valve element (2).
