Clock transmission coupling

A transmission coupling (100), especially a timepiece transmission coupling, for the mechanical linkage of at least one first part (2A) of a first shaft at least movable in rotation about a first axis(A2) to at least one second part (3A) of a second shaft at least movable in rotation about a second axis (A3), the first and second axes being parallel or substantially parallel, the transmission coupling including the at least one first part (2A), the at least one second part (3A), and at least a first elastic return system (15, 16; 18; 16a; 16b; 16c; 16d; 111a, 111b; 221, 222, 223, 224) arranged so as to limit or cancel out the play between the at least one first part (2A) and the at least one second part (3A), and connecting the at least one first part (2A) and the at least one second part(3A). 种钟表传动联轴器，其用于将至少能围绕第轴线(A2)旋转运动的第轴的至少个第部分(2A)机械地连接到至少能围绕第二轴线(A3)旋转运动的第二轴的至少个第二部分(3A)，第轴线和第二轴线平行或大体平行，传动联轴器包括：第轴(21)的至少个第部分(2A)；第二轴(31)的至少个第二部分(3A)；以及被设置为限制或消除第轴的至少个第部分(2A)和第二轴的至少个第二部分(3A)之间的间隙的至少个第弹性返回系统(15，16；18；16a'，16b
