It may depend on how you define "eternal torment".
The Eastern Orthodox understanding of Hell, for example, describes it as a state of being while in the midst of God's all-loving, all-merciful presence. That is, in the words of St. Isaac the Syrian, Hell is the "torment" of God's love. The anguish felt is to be in the presence of love, and feel the remorse of having sinned against such love.
Though what you're more likely to find is that many denominations don't make it a point to try and pin down or define what "Hell" is; understanding that Scripture itself is rather ambiguous on that point. Believing there is a "Hell", yes; but understanding that "Hell" is a somewhat nebulous concept.
Of course there are churches and denominations that are pretty specific about Hell. Fundamentalist and American-style Evangelical churches generally are pretty emphatic about what Hell is, even describing it as active divine torture.
Basically this: There really is no, and never has been, a solid consensus on the doctrine of Hell in Christianity. While Christians have put forward creeds and confessions over the centuries to say, "We most certainly believe this", Hell just doesn't get that sort of treatment.
