The invention relates to a method for correcting a misalignment of at least one shafting of a powertrain on a test bench, where at least one piezoelectric force sensor is arranged in a path of force via which a force flow can be transmitted between a load unit of the test bench and a drive unit of the powertrain or the test bench during a transmission of power via the shafting, comprising: performing a force measurement in at least one plane and/or perpendicular to the at least one plane which is intersected by a rotational axis of the shafting and may be substantially perpendicular to the rotational axis; analyzing a measured value or a measured value progression of the force measurement for detecting a misalignment of the shafting; determining target values for a position correction of the load unit or the drive unit in order to minimize the misalignment; and outputting the target values.
