I have added HashedControlPassword to my torrc and restarted, and put the password in DarkMX the password box for External Tor Proxy / Control Connection but it still doesn't seem to be working. The ports match my torrc settings. When I try to get info from a different instance of DarkMX it fails, only outgoing connections seem to work. Does HashedControlPassword work for DarkMX?

For the DarkMX external Tor client option, only the cookie-file method of control port authentication is supported at the moment.

I will get the other two methods implemented very soon.
