Since each convex tooth in most flexible couplings on the market is the same shape, it can only be used in occasions where there is no position alignment requirement for the assembly of the driving shaft and the driven shaft. For occasions where the driving shaft and the driven shaft need to be rotated to a specific position before they can be connected, the current flexible couplings still cannot meet the requirements. Therefore, it is an urgent problem to design a coupling that has position alignment requirements for assembly, smoother transmission, and convenient separation. Summary of the invention
