Glad you got the coupler sorted.
I very nearly had coupler "issues" on the ForkenSwift, but not from breakage.
The 2 set screws on the FS don't seem to prevent the two halves from sliding away from one another, and on 2 occasions, I have peeked in the inspection window (which was intentionally cut into the transmission bell housing to keep an eye on the coupler) and noticed .... THIS...
Hanging on by its fingernails!!!
Amazing I didn't wreck it!
