Benko will be included in the Devils’ line-up for their Premier League match against Glasgow at the St Boniface Arena on Friday evening (7.15pm).
He replaces injured reserve Sam Chapman.
Devils co-promoter Ashley Taylor said “Roland was all set to re-join us this season but a domestic situation arose with his family which meant he had to stay behind in Hungary to help support them.
“That has now been resolved and we are pleased to welcome Roland back to Plymouth.
“He has some unfinished business as far as we are concerned. His away form was less than spectacular, but Roland was gating well and getting some good scores at home.
“This season he will be back with a greater knowledge of away tracks, so we are looking forward to improved performances away from home.”
The new Devils team, with averages, is: Kyle Newman 7.35, Ryan Fisher 6.74, Morten Risager 6.55, Jack Holder 6.28, Todd Kurtz 5.96, Sam Simota 5.67, Roland Benko 3.00.
