Yes, technically adultery is committed by adults, but the connection between these two words ends there.
Adultery comes from the Latin word adulterare, "to pollute or corrupt," while adult comes from the Latin verb adolescere, meaning "to grow up."
adolescere = to grow up
adolescens (present tense) = grows up
adultus (past tense) = grew up
So there you go — an adult is someone who has finished growing up, and an adulterer is someone who pollutes or corrupts.
