Constrain one actor to a specific spot on another, moving actor

I am working on a game where the player character is made up of several actors constrained to a hitbox (legs, body, head, arm, arm). The hitbox spawns them into the game and they are constrained relatively using a global attribute that tracks the hitbox's position.
One arm is basically just a gun and will not have to move. The other arm is causing me problems.
The way my partner (the artist) has envisioned this is that one arm is always "up" - the gun arm. The other carries a melee weapon of some sort (in this case, a sword) and is able to be swung independently.
I was able to successfully constrain the sword to where the hand would be, but once I tried making the arm rotate as part of a walk-cycle I realized my implementation is broken (as is the arm rotation, but I know how to fix that one).
How do I constrain my sword actor to end (the "hand") of the arm actor, rotating by the same amount when the arm moves?

The answer is quite straightforward, but not very intuitive and involves a little bit of trigonometry - but to save you time I made a machine that works it out for you.

That is extremely helpful!
Mr. Socks also has a handy articulating arm demo.
