Yes, they were called Rotoflex couplingsDidn't Triumph and Hillman use these back in the 60's and 70's?
Triumph GT6 MK11 and early MKIII had them on the rear drive shaft a and the 1300 FWD had them as well on the driveshafts
Changing the GT6 Rotoflex was a bit of a mission, the coupling came banded so you could fit it and then cut the banding once installed.
There was a special Churchill tool to decompress them which I used to have along with a shed load of other Triumph tooling but a messy divorce saw me lose them
I have made do with BIG jubilee clips to decompress the couplings
I worked out you could cut the old Rotoflex off if it already hadn't fallen apart, cut the banding on the new coupling and leaver it over the ears on the outer shaft and then recompress it to get the bolts in.
Why? Getting the outer shaft out of the hub and back in was a proper mission
