I'm NOT an electrician as you asked, for but did spend much of my life career as an electrical power distribution design engineer who developed plans and specs which electricians followed and had to attend NEC educational Seminars and Workshops on a regular basis. WOW that's an expensive tool, Id hate to have to buy one lol but I'm retired and not an electrician either..

PROPER TORQUE is an important and critical part of electrical connections moreso then lay persons understand. Those values are the result of material science and engineering and aren't specified just for the heck of it by the manufacturers. If too loose carbon (and resultant heat developing resistance) and arcing and burning and/or loosening can happen, but if too tight the wire or lugs may be damaged.

I'm rusty on the latest codes HOWEVER although while the correct torque values may be specified (for good engineering reasons) I'm not aware of any requirements of what specific tools must be used or who must own them etc. ITS JUST THAT CONNECTIONS MUST BE TORQUED CORRECTLY SINCE IF NOT THERES A FIRE OR LIFE RISK !!!!!!!!!!!! I cant imagine proper torque to be a bad thing AS IT CAN SAVE A LIFE OR PREVENT A FIRE. However I have no idea what the latest code may say about who must own or use whatever tools ONLY THE CONNECTIONS BE PROPERLY TORQUED and as an electrical engineer I sure agree 100%

That being said and before anyone wants to flame on me or the NEC, the main thing is they be checked periodically and kept "tight" even if the precise exact perfect numerical torque value isn't exactly achieved IE keep them tight not over tight but never loose NOW THATS JUST COMMON SENSE EVEN IF YOU DONT OWN A TORQUE DEVICE Well Duhhhhhhhhh lol

NOTE there are different codes and/or different versions which may or not have been adopted in certain jurisdictions SO CHECK WITH LOCAL AUTHORITY not any of us here. There may or may not be authority or codes where you live DONT ASK ME IT YOUR HOUSE AND YOUR LIFE AND YOUR RISK to wire or torque or never torque or check as you well please.

It will be interesting to see the opinions of other trained professional electricians and electrical engineers on the question of proper torque, good or bad?? necessary or not??? what the codes say??? does anyone even care lol

Take care n be safe yall, best wishes n God Bless
