<p>The coupling unit (10) has two elements (20, 30) provided with two diaphragms and coupled to two rotary parts (2, 3), respectively. A torque-transmission emergency device includes a bayonet system with a protuberance (50) secured to one element and co-operating with an angled groove (60) secured to the other element by a thrust-and-rotation movement. The coupling unit includes both axial clearance in compression together with axial clearance in traction, and circumferential clearance between each protuberance and walls defining the corresponding angled groove.</p> |
