A torsion element includes a torsionally soft, flexurally stiff torsion rod, a plurality of piezoceramic fibers wound on the torsion rod, and a plurality of electrodes wound on the torsion rod cross-wise at an angle a with the respect to the plurality of piezoceramic fibers and electrically contacting the piezoceramic fibers. In addition, a torsional actuator including such a torsion element clamped in a fixed bearing and the free end(s) being operatively connected to a gearing for converting the motion.
