The accuracy of axial alignment of rotary shafts which are connected to each other by face gears is determined by micrometer screws which are moved into contact with annular control surfaces of the shafts. The control surfaces are normal to the axes of the respective shafts and, if their planes are not exactly parallel to each other, selected teeth of the mating face gears are elastically deformed to a greater or lesser extent to thereby tilt at least one of the shafts with respect to the other shaft until the two axes are accurately aligned with each other. The elastic deformation of selected gear teeth can be effected by bolts and nuts which connect the two shafts and extend in parallelism with their axes or by a composite annular clamp whose arcuate sections engage tapering surfaces on the flanges of the shafts and are held together by bolts which can tilt the shafts relative to each other by changing the width of gaps between neighboring sections.
