Abstract: A stirring apparatus (1), with a stirring tool and a measurement apparatus (2) for the measurement of torque that is introduced during stirring into the medium that is to be stirred, is mounted on bearings on its holding device (4) in such a way that it can rotate or pivot around the axis of rotation of the stirring tool, and is supported against the direction of rotation of the stirring tool. The measurement of the torque is carried out by means of a measurement value sensor, which records the reaction force of this support directly or indirectly. A measurement value sensor that is fixed in position can be used for the measurement of the torque, and the measurement of the torque requires only a single pivot bearing (11).
