one coupling part having pins arranged parallel to the axis and entering holes in the other coupling part

Full Title

Yielding couplings, i.e. with means permitting movement between the connected parts during the drive (couplings disconnectable simply by axial movement F16D1/10; slip couplings F16D7/00) > Universal joints in which flexibility is produced by means of pivots or sliding or rolling connecting parts > one coupling part having pins arranged parallel to the axis and entering holes in the other coupling part
