can you post detail pictures of the parts you are trying to mate? I'm not familiar with the paratool adapter
I don't know if this will help or not. Find a socket that comes closest to fitting your tool. Spray the tool with Pam cooking spray then fill the socket almost full J-B Weld then put the socket on the tool. When the J-b Weld dries remove the socket and it will be a perfect fit to your tool the cooking will act as a release agent and will keep the socket bonding to the tool.Mike
