Looks a lot like the harmonic drive that failed in one of our machine's tool changers. We bought the machine used and the previous owner tried to weld it back together. Their repair lasted for about 6 months after we bought it. Our break wasn't quite as bad though because ours only went around the base of the cup and wasn't split through the splines like yours. From the looks of the repair on ours their weld only held in a couple of small spots, most of it probably was never held or broke almost instantly.

[EXTERNAL EMAIL] Be sure links are safe. I bought an FHA-17C actuator from eBay. It was cheaper than normal, for parts or not working. It clearly had the cables cut off, so I decided to gamble. It turns out that things were worse than I hoped. https://photos.app.goo.gl/p3SL2Bwv2b9yd5XJ9 I am seriously considering trying to make a new flexspline.
