Hughes told City's website: "I'm delighted to welcome Glyn here. He has a great pedigree, has been a manager himself and did a great job at Blackburn.
"He will be a good link for the guys coming from the Academy and them being well prepared enough to join the first team. He is great in that role and will bring a lot to us.
"Glyn is a pro licensed coach, as all my senior coaching staff are and that is important, because it means the players are getting the right quality of work. He will be a great asset for us.''
With Hodges now in place, Mark Hughes has finalised his backroom staff after Mark Bowen, Eddie Niedzwiecki and Kevin Hitchcock also moved from Rovers this summer.
Of his first team and goalkeeping coaches, Hughes said: "I was delighted to have been able to bring Eddie and Kevin in earlier in pre-season.
"They're top quality guys who I've known for many, many years and they are the best at what they do, in my opinion. So I'm delighted that the backroom staff is all place.
"What they all have and what I demand is a massive work ethic and they give me that. They're my voice in the dressing room if I'm not there."
