Does anyone know the correct torque?

Monitor the coupling for unusual vibrations and if you are going to re wire the bolts also check the torque on the coupling bolts and the coupling to shaft set screws.

It appears (from the invoice) that they went overboard and disconnected the shaft, removed the stuffing box, cleaned it up, then reassembled everything. I noticed when I was closing the engine thru-hull that the safety wire on the bolts that secure the shaft had been removed and not replaced very neatly. (A six inch tail was hanging from the coupling.) I'm going to redo the wiring, but I'm wondering whether it's necessary to realign the shaft with the engine after disconnecting the shaft from the coupling. My intuition is that the answer is no, but perhaps that is wishful thinking. I thought I would consult all of the experts here for a reality check. Let me know if you have some thoughts.
