The MULTI MILLION DOLLAR QUESTION about BH plasma jets and discs.

How the plasma jets and discs are formed without being sucked in to the BH. see: THIS   "How to escape a black hole"

( HOW? due to Fermion repelling BH, by spin flip of positrons and electrons, according to Q-FFF Theory) ) see: Tidal Star Disruption Events (TDE) by Fermion Repelling Black Holes in Quantum FFF Theory.

The torque arises from the twisting of magnetic field created by the plasma disc itself ( not the inertia less BH)
The gist of this effect is the multi million dollar question, because it shows the solution for all our energy problems and it is a clear quest for propeller shaped fermions ( or better a "rigid string theory").

 Parfrey said  "even though it doesn't necessarily contribute that much to extracting the black hole's rotation energy," , "is possibly directly linked to the electric currents that twist the jets' magnetic fields."
The team intends to better model the process by which electron-positron pairs are created in the jets in order to study the jets' plasma distribution and their emission of radiation more realistically for comparison to observations.

"How can the energy in a black hole's rotation be extracted to make jets?" said Kyle Parfrey
"This has been a question for a long time."
Less understood, though, is how black holes purge energy locked up in their rotation, jetting near-light-speed plasmas into space to opposite sides in one of the most powerful displays in the universe. These jets can extend outward for millions of light years.
