May I suggest two approaches:

1) don’t mess with the trimmers. Assume that they are ok the way they are.

2) If you do decided to adjust them:

 a) use a small needle nose pliers and be careful

b) make a tool. Drill into a rod of some sort (perhaps brass) and get out your tiniest needle fie and make the hole square. Then: advertise coupler alignment services as the only known facility that’s properly equipped to do the job.
