A twisting device for power looms comprises oppositely moving heddle supporting rails, two lifting heddles arranged on the heddle supporting rails for standing threads, a semi-heddle for turning threads controlled separately from the heddle supporting rails. It also has a coupling part having magnetic properties and arranged so that the semi-heddle is supported through the coupling part on both the lifting heddles in a longitudinally displaceable manner, and two countercoupling parts having magnetic property and alternatingly cooperating with the coupling part. One of the countercoupling parts is movable together with one of the heddle supporting rails while the other of the countercoupling parts is movable together with the other one of the heddle supporting parts.
