ABSTRACT:
An anti-twist device retains an actuating motor (10), which is placed in a force-fitting and/or form-fitting manner onto the projecting driveshaft (22) of a pivotable shut-off flap (62) of a gas transport tube (34), in particular of an HVAC tube or flue gas tube for a building, in a longitudinally moveable manner. Arranged at an adjustable axial distance (a) from the driveshaft (22) is at least one clamp (36) which secures the actuating motor (10). The parallel limbs (46) of the preferably substantially U-shaped clamp (36) are of resilient design, wherein in each case one end-side, inwardly projecting latching lug (48) is formed for holding down the actuating motor (10).
