The invention relates to a device for reducing loads in a drive train (10 - 30) of a wind turbine, comprising a machine support (60). The wind turbine is provided with sensor means (80, 82) for detecting at least one variable characterizing vibrations and/or misalignments in the drive train (10 - 30), controllable damper means (25) for producing at least one adjusting torque which compensates at least one torque (M) associated with the load in the drive train (10 - 30), and actuating means (70) for actuating the damping means (25) based on the at least one variable detected by the sensor means. The invention also relates to a corresponding method.
