How to get Coupon Discount Amount by Coupon code?

Question

I used the following code to retrieve the coupon code for the current order:

$Coupon_Code = $order->getCouponCode();

It works fine, but I want to get the discount amount for a certain coupon code, using this code:

$Coupon_Code = $order->getCouponCode();
            
$oCoupon = Mage::getModel('salesrule/coupon')->load($Coupon_Code, 'code');
$oRule = Mage::getModel('salesrule/rule')->load($oCoupon->getRuleId());
var_dump($oRule->getData());
$Coupon_Discount =$Coupon_Code['Discount Amount'];
