If it is like the one I just replaced on my 30-1, the two halves of the coupler are bolted together with four bolts which have lock washers. They are not set up for a lock wire. The aft part of the coupler is positioned on the shaft with a key and is held in place with two square headed lock bolts. These fit into dimples on the shaft and have provision for a lock wire. I ran the wire through one and then twisted it and ran it over to the other, ran through that and twisted some more.

When you say perpendicular to the coupler I can't picture if that is perpendicular to the shaft or inline with the shaft. I think you're describing inline with the shaft which makes me wonder why using a cotter pin wouldn't work? Either way, lock wire should normally be routed in a figure 8 such that loosening of either or both of the bolts will result in the tightening of the wire.

Shaft is seated in coupler and two square head, drilled, cup pointed bolts go into dimples in shaft..i know that proper technique is to properly safety wire the bolts through drilled heads so can't come loose. But, when seated the drilled holes in bolt heads are perpendicular to coupler and there is absolutely no room to properly safety wire these.. I could remove bolts, drill opposite faces of bolt, reinstall and safety wire, BUT, I was thinking of getting proper size cup head set screws instead and stacking two in the coupler to lock them instead.
