The former Bury youngster – who made 29 first-team appearances for the Shakers – has signed an initial 12-month deal with a further one-year option.
And he will start out as part of Steve Stone’s Under-23 squad as their second new arrival so far this summer following the earlier arrival of former Curzon Ashton defender Joel Senior.
His first-team debut came in August, 2017 and the 19-year-old went on to make 14 appearances in the 2017/18 campaign.
Cooney then played 15 times at first-team level last season, including nine times in League Two as cash-strapped Bury defied off-the-field problems to win promotion back from League Two at the first attempt and six times in the Checkatrade Trophy to help the Shakers reach the semi-finals.
