The elements are held together by at least one tensioned, flexible coupling element strong in tension which describes a circular arc and is anchored at each of its ends in an endpiece. Adjusting structure is provided in order to alter the distance of the endpieces from the center Z of the circular arc and hence the radius of the segment gear.
