[Public-List] shaft coupling parts in bildge

[Michael Connolly]

Greg, Welcome to the group.
The three thngs are / should be bolts including nuts which hold the coupling flanges together. Both rigid and flexible couplings use nuts and bolts to hold them together. Most likely you have not found the nuts yet. Hammering the bolts in place is NOT sufficient to hold all together properly while under power.
